NAG, optimization and finance [2 webinars: 11 minutes, 15 minutes]
This webinar discusses the use of the NAG Library for optimizing financial portfolios. Part 1 introduces optimization and illustrates the importance of choosing the appropriate algorithm by using the so-called Rosenbrock function to compare the performance of a NAG routine and a simpler but less sophisticated algorithm. Part 2 briefly explains the Markowitz model as a method for obtaining portfolios that correspond to a given return with minimum risk, and presents demos which implement this method in Excel® and MATLAB® by calling NAG routines. See also this webinar, which explains in more detail how to call NAG routines from Excel in order to perform portfolio optimization.
